Be it known that I,A HoWAaD E., CorFIN, a citizen of the United Statesof America, re -`siding at Detroit, in the county of Wayne and State ofMichigan, have invented cer- A- tainv new anduseful Improvements inRunning-Boards for Automobiles, ofwhich the following is aspecification, reference being had therein to t e accompanying drawings,

The invention'relates to running boards for automobiles and consists inthe construction as hereinafter set forth.

In the drawings-Figure l is a plan View ofthe structure; Fig. 2 is asideelevation 5' and Fig. 3 1s a cross section.

It is the object of the invention to obtain alight, strong,noncorrosive"'inetallic running board, and one Which possesses a highlyornamental appearance. This I accomplish by forming the body portion ofthe board of a steel plate A, having down-turned marginal fianges B. Thetop of the plate is then covered by a facing C preferably-- of sheetaluminum, which is corrugated or otherwise embossed. Thisplateis securedin position by an angle 'section'frame D, .having one wing E extendingoverV the aluminum facing, and the other wing F extending downwardadjacent to the flange B. 'l`h1s frame is preferably formed of brass,and may be secured by any suitable means, such as the rivets G.
